From 903b3ff3564f19c624e90c48ec2d7fcfef6cce8e Mon Sep 17 00:00:00 2001 From: Tim Crawford Date: Tue, 28 Feb 2023 07:55:48 -0700 Subject: mb/system76/adl: Disable Intel ME by default Disable the CSME by default now that S3 is used instead of S0ix. The CSME will not go into a low power state during S0ix when it is disabled. This prevents the CPU from reaching C10 and so increases the power usage during suspend compared to leaving CSME enabled. (This was measured to be a ~2W different on TGL-U.) In S3, the state of the CSME doesn't matter because the CPU will be off.
